## Gauth

Gauth is a study app that turns homework problems into teaching moments. A student photographs a question or pastes it into the web calculator, and the AI returns a structured solution that walks through the reasoning instead of just giving the final number. Coverage is deliberately broad: maths and calculus, statistics, physics, chemistry, biology, economics, literature, business, writing, social science and general-purpose subjects, which makes it useful across very different curricula rather than only for algebra drills.

The platform pairs two layers of help. The AI layer answers quickly and free of charge for a limited number of questions, with detailed step-by-step explanations and tips on the concepts behind each step. On top of that sits a tutor service that connects students to real verified tutors around the clock; the company advertises tens of thousands of experts, high satisfaction rates, fast turnaround on hard problems and access to a large question knowledge base. Gauth also offers an Academy section with courses and a newer Gauth Atlas experience that turns subjects into explorable visual maps grounded in cited sources.

Gauth is available on the web and as a mobile app on both iOS and Android, where it has a large review base. It follows a freemium model: a free tier covers everyday questions, while Gauth AI Pro unlocks unlimited answers and premium features via a free trial followed by a paid subscription. Exact plan prices and trial conditions should be confirmed on the official site.

**Pricing & Plans:** Freemium. A free tier answers a limited number of questions, and Gauth AI Pro offers unlimited answers and premium features, typically starting with a free trial before a paid subscription. Check the official site for current prices and trial terms.

- **Photo-based question solving:** Upload or paste a homework question and receive an answer in seconds, covering maths, sciences, business, writing and social sciences.
- **Step-by-step explanations:** Solutions break the problem into clear steps with reasoning and conceptual tips, so students learn the method rather than only the result.
- **24/7 human tutor service:** When AI output is not enough, students can escalate to verified human tutors for personalised guidance, including help with advanced problems.
- **Gauth Atlas visual learning:** An explorable visual map turns a subject into zoomable layers of related ideas, with each image traced back to a real source.
- **Cross-platform access:** Use Gauth in the browser or through the iOS and Android apps, with an Academy area for structured courses and a large study-resource library.

**Strengths:** Works across a very wide range of subjects, not just mathematics; Step-by-step explanations focus on understanding rather than answer copying; Human tutors are available around the clock for problems the AI cannot resolve; Free tier plus mobile apps on iOS and Android make it easy to try

**Limitations:** Unlimited answers and premium features require the paid Gauth AI Pro subscription; AI-generated solutions can still contain mistakes on unusual or ambiguous problems, so they should be checked; Reliance on instant answers can undermine learning if used without attempting the problem first

## LangPDF

LangPDF is an online tool focused on producing professional PDF documents from short text prompts. You start by describing the document you want — an invoice, resume, contract, report, proposal, quote or letter — and the platform assembles a structured, downloadable PDF. A library of templates is included so you can begin from a professional layout and adjust it rather than designing everything from scratch.

Typical workflows include generating business documents without manual formatting, customizing ready-made templates, and standardizing recurring paperwork such as receipts, product requirement documents, reports and standard operating procedures. Everything is done in the browser: you preview the result online and download it when it looks right.

The pricing is tiered by output volume. A free plan covers occasional needs with a small monthly quota, while Pro and Team tiers raise the number of documents you can generate each month for regular professional or high-volume business use. Exact quotas and prices are listed on the official pricing page.

**Pricing & Plans:** Freemium with tiered plans by monthly output volume: a Free plan for occasional use (about 5 documents per month), a Pro plan for regular professional output (about 300 per month) and a Team plan for higher-volume business use (about 1,500 per month). Check the official pricing page for current details.

- **Prompt-to-PDF generation:** Describe the document you need in plain language and get a finished, structured PDF back.
- **Professional template library:** Start from ready-made layouts for invoices, resumes, contracts, reports, proposals, receipts and more.
- **In-browser preview:** Preview the generated document online and download it only once it looks right.
- **Business-ready document types:** Covers invoices, resumes, contracts, reports, quotes, letters, SOPs and product requirement documents.
- **Tiered output plans:** Free, Pro and Team plans scale the number of documents you can generate per month.

**Strengths:** Turns a simple prompt into a finished, downloadable PDF; Includes templates for common business documents; Browser-based with online preview before download; Plans scale from light free use to higher business volumes

**Limitations:** Focused on document generation rather than PDF editing or translation; Free tier has a limited monthly output quota
